Method and device for clearing fingerprint data

The embodiment of the invention provides a method and device for clearing fingerprint data, relates to the technical field of communications, and does not influence the fingerprint data of other operating system when deleting the fingerprint data corresponding to a certain operating system. The method is applied to terminal equipment, and the terminal equipment comprises at least two operating systems. The method comprises the following steps: receiving a fingerprint clear instruction, wherein the fingerprint clear instruction is used for indicating to clear the fingerprint data; determining afingerprint identifier of a to-be-cleared fingerprint according to the fingerprint clear instruction, wherein the to-be-cleared fingerprint comprises at least one fingerprint; and if the to-be-cleared fingerprint is a fingerprint corresponding to a current activation system, deleting fingerprint feature data of the to-be-cleared fingerprint according to the fingerprint identifier of the to-be-cleared fingerprint, wherein
